The author has developed a simple, efficient and eco–friendly convenient general method for synthesis of 3,5–disubstituted–1,2,4–triazoles and 1,3,5–trisubstituted–1,2,4–triazoles from 3–monosubstituted–1,2,4–triazoles and 1,3–disubstituted–1,2,4–triazoles respectively using tetrabutylammonium iodide (TBAI) as catalyst and TBHP as oxidant under mid reaction conditions. This method provides structurally
作者已经开发出一种简单,有效且环保的便捷通用方法,可从3–3合成3,5–二取代–1,2,4–三唑和1,3,5–三取代–1,2,4–三唑。在中间反应条件下,分别使用四丁基碘化铵(TBAI)作为催化剂和TBHP作为氧化剂,分别使用单取代的1,1,2,4-三唑和1,3-二取代的1,2,4-三唑。这种方法提供了结构多样的3,5–二取代的1,2,4–三唑和1,3,5–三取代的1,2,4–三唑,收率非常好。3,5–二取代的1,2,4–三唑和1,3,5–三取代–1,2,4–三唑衍生物是具有生物学和药学活性的分子,因此,该方案可以在药物化学中广泛应用和有机化学。
